338 BOTANY. Oregon to Lake Winnipeg, Wyoming Territory, and Lake Superior. Utah, Colorado, and Arizona, but not sent from California. This and the last have a continuous (not jointed) stalk, such as is found in W. obtusa and its immediate allies, but the indufsium is rather that of W. Jlvensis, though very much reduced. Of the Texan plant (C. Wright, Nos. 830 and 2120), doubtfully referred to W. obtusa, I have its yet seen no specimens in a condition for satisfactory examination. Sir W. J. Hooker had placed his specimens in the same cover with W. Peruviana, and that species is now considered a var. of W. obtusa by Mr. Baker. Suboedee. SCHIZiEACEiE. XVI. ANEIMIA. Swartz. Sporangia ovate, sessile, opening longitudinally, furnished with a trans¬ verse apical complete operculiform ring, placed in two rows on the back of the very narrow branchlets of the two long-stalked panicled lower branches of a pinnately divided frond, the fertile branches in a few species entirely distinct from the sterile frond. Veins free or anastomosing.—A genus of about twenty-seven species, none of them large Ferns, mostly South Ameri¬ can, one being South African, and two coming within the borders of the United States. Aneimia mexicana, Klotzsch. Rootstock creeping, densely covered with narrow subulate blackish chaff; fronds scattered, on slender stalks, pinnate; the two lower branches fertUe, long-stalked, glandular-puberulent, bipinnate with densely clustered fructification; the rest of the frond like the sterile ones, deltoid-ovate, simply pinnate; pinnse about six pairs and a rather large terminal odd one, short-stalked, broadly ovate-lanceolate from a rounded or slightly cordate base, sub-coriaceous, smooth and somewhat glossy ; midrib very distinct; veins free, oblique, parallel, closely placed, once or twice forked, the vein- lets running out into fine serratures.—Linnsea, xviii, p. 526. Kunze, Die Farrnk. ii, p. 75,1.131. Hooker, Ic. Pl. x, t. 988. Western Texas, Undheimer, Wright. Also in various parts of Mexico. Plant a foot or eighteen inches high, the common stalk fully half of this height, smooth, except for a few scales near the base. The pinnffi are 2-2i inches long and about one-third as broad, sub-coriaceous iu texture, and finely striated by the slightly raised veinlets. A. adiantifolia, Swartz, with a sub-tripinnate sterile segment, occurs in Florida, and is common in the West Indies and Tropical America.
